DeBenedictis 1964 Feb23 Wreck Bay, Isla San Cristobal, Galapagos. quite way. The ♂ is grey-green, stepped like Santa Cruz ♂s, and the ♀ is a brown color of the same type, fairly red on the head and reminiscent of the Hood form. Saw male chase a ♀ who assumed the stiff egged tail up (+ around) ejection posture ( the function like C. carpenteri). The ♂ did not copulate + the two lizards soon parted. The ♂ bob is quite complex, but seems to be something like the below; ↑ not sure sure of the /4 height true → low + the # of final low bobs, but something like this is clearly indicated. When I got back to Wreck Bay an Ecuadorian showed me a black lizard he had found on some large trees in the centre of town. These proved to be Gonatodes !. The (♂) is black with a zig zag yellow vertical strip and yellow spotting on the breast. The(♀) is grey, with the same pattern indicated in light and shade. They ran into deep fissures in the rocks when I approached and I could not catch any. Saw them c. 5 P.M. Spent the rest of the evening skinning. After dinner we talked to Jacob [illegible] friend who lives (periodically) in Wreck Bay. He said he had last seen Tortoise in 1952 (a few) and believed they may st./ll be in extant in the NE part of the island. Final goats and pigs are not common here, as they are heavily hunted and do not do much to the vegetation. 168
